General Purpose Tanks

Polyethylene general purpose tanks are used for storage of potable water, waste water, chemicals, or solids. Because they have superior mechanical properties, high stiffness, excellent low temperature impact strength, and outstanding environmental stress crack resistance, they stand up well in tough environments.

General purpose tanks have a high resistance to both physical and chemical attack. This makes them excellent containment vessels for a wide range of diverse contents from aggressive and corrosive chemicals to food products. General purpose tank contents are typically industrial chemicals, liquid food products, potable water, or waste water.


The overall general toughness and excellent chemical resistance of polyethylene to a wide array of wet and dry industrial chemicals and food products makes it ideally suited for storage tanks. Dura-Cast general purpose tanks are made with FDA-compliant UV stabilized polyethylene. They comply with U.S. Food & DrugAdministration regulation 21CFR 177.1520 (1) 3.1 and 3.2 for storage of potable water. This permits it to be used as an article that can be in contact with potable water or food products.

General purpose tanks can be used indoors or outdoors. Because the resin is UV-stabilized, it will not breakdown under harsh outdoor weather conditions or under prolonged exposure to fluorescent lights. The natural opaqueness of polyethylene permits easy viewing of content levels.

We manufacture tanks through rotational molding, resulting in a tank that is a single piece construction, seamless, has a consistent tank wall thicknesses, and is stronger at wall joints and corners.
